Ronald Cohen's research aims to describe the role of chemical reactions, human activities and ecosystem functions as they affect Earth’s climate and as they relate to unhealthy levels ozone and fine particles. His research on the chemistry of organic nitrates established that these molecules are the main path for removal of atmospheric nitrogen oxides on the continents. His research using satellite measurements of nitrogen oxides has established new methods for achieving accurate interpretation of trends in urban chemistry: http://behr.cchem.berkeley.edu/. In his newest research project, BEACO2N, he is building a neighborhood scale long-term observing system for tracking CO2 and air quality: www.beacon.berkeley.edu. This project was one of three “Climate Data in Action” efforts recognized in the Obama administration’s Climate Data Initiative in summer 2014. The project is following trends in CO2 and related gases and aerosol in cities including the Bay Area, Pasadena, CA, Houston, TX, New York and beginning in 2019, Glasgow, Scotland.

The White House has given a public nod to a ground-breaking UC Berkeley air-monitoring project and its new collaboration with a Colorado public media platform, which aims to build a citizen-science story-corps to help monitor carbon emissions in the Bay Area.
Using inexpensive detectors that can fit inside a shoebox, UC Berkeley chemists are installing carbon dioxide and other air pollution sensors in 40 sites around Oakland to explore how detailed, neighborhood-by-neighborhood information can help communities monitor greenhouse gas and other harmful emissions.
UC scientists built and worked in towers — some as tall as 1,500 feet — as part of the largest single atmospheric research effort in the state. The data they’ve collected will guide policymakers dealing with air pollution.
